I think Blanco knows she's in really deep doo doo. The Clintons showing up down there to grandstand, and Blanco who has all but hidden every day, fuel my suspicions.
My husband is based at NAS Belle Chasse just south of New Orleans. Everyone working and living aboard the NAS was evacuated out on Saturday. Every single person. Aircraft were flown to outlying areas, too. This is not local government; it's federal gov't executing an excellent evacuation. Given that it was built at sea level or slightly above, it wasn't affected by severe flooding, however the flooding on the local roads off-base are a large part of the reason the NAS isn't up and running right now.
Unfortunately, the MSM will keep that info from getting out.
